Struct Metadata 

pub struct Metadata {
    pub geographical_extent: Option<GeographicalExtent>,
    pub identifier: Option<String>,
    pub point_of_contact: Option<PointOfContact>,
    pub reference_date: Option<String>,
    pub reference_system: Option<ReferenceSystem>,
    pub title: Option<String>,
    pub other: HashMap<String, Value>,
}

The metadata member of a crate::CityJSON object (§ 5 Metadata).

The six members below are the ones the core spec names. They are not the only ones a valid document may carry: metadata.schema.json’s metadata object declares those six under properties and then stops – there is no additionalProperties: false, unlike (say) transform or geometry-templates, which both do declare it. So any further member is legal CityJSON, and the spec itself points at the MetadataExtended Extension as the place to put more.

Hence other: without it every such member is silently dropped on the way through. Real files rely on this – every 3DBAG dataset carries fullMetadataUrl and version in its metadata (see tests/data/small.city.jsonl), and before this field existed both simply vanished.

Fields

geographical_extent: Option<GeographicalExtent>

identifier: Option<String>

point_of_contact: Option<PointOfContact>

reference_date: Option<String>

reference_system: Option<ReferenceSystem>

title: Option<String>

other: HashMap<String, Value>

Every metadata member the core spec does not name, kept verbatim.
